Title: Disproportionation of aromatic hydrocarbons
Inventor: GOLDUP ALAN
IPC: C07C6/12
Filed: 1964-10-09
Abstract: The disproportionation of an ethyltoluene to toluene and 3,5-diethyltoluene is effected in the presence of a complex of a solid Friedel-Crafts compound and a hydrogen halide under anhydrous conditions.  The preferred feed is a reformate fraction boiling in the range 161-168 DEG C. which also contains mesitylene. The mesitylene is unchanged but forms a complex with the catalyst as does the diethyltoluene. The complex product is preferably extracted with a solvent, e.g. n-heptene to remove toluene and the complex decomposed with water to recover the mesitylene and diethyltoluene. The molar ratio of ethyltoluene to aluminium chloride may be 1-10:1 and reaction is effected at 0-50 DEG  C.  The preferred catalyst is aluminium chloride-hydrogen chloride.

[Also in Division H4] Means for detecting errors in synchronism between data pulses received from tape or punched readers and timing pulses comprises a number of bistable units set by the output of one or more "and" gates receiving the data and timing pulses and interrogated regularly. As described, a data pulse normally overlaps three spaced strobe pulses, but if it occurs early or late relative to these pulses then only two pulses, or in extreme cases one pulse, will be delivered from an "and" gate. In one embodiment, the output of this single "and" gate feeds a two-stage binary counter which delivers an output to one terminal if it has been set to two, and to another if set to one. Other embodiments having separate "and" gates for the three strobe pulses distinguish between a late and an early data pulse, and the signals indicating these conditions may be used to retard or advance the strobe pulses by shutting off, or adding, a pulse to a four stage binary counter used to select three strobe pulses from sixteen timing pulses occurring in each data pulse period.

Abstract: 1,070,727. Magnetic recording &c. apparatus. M. STAAR. Nov. 4, 1963 [Nov. 5, 1962], No. 43430/63. Heading G5R. Sound-recording tape is stored in a cassette, the length and rigidity of the tape being such that it can be wound freely on itself in concentric turns inside the cassette, the only drive for the tape being provided by external elements which introduce the tape into the cassette by pushing the tape through a passage through which the tape both enters and leaves the cassette. Cassettes.-In Fig. 3 the cassette 1 has a hollow interior 2 and a passage 4 tangential to the interior 2. A strip 6 may be secured to the cassette and may carry a friction element to act on the tape, Fig. 2 (not shown), or may carry a contact 10 adapted to touch another contact 11 when one of two apertures near each end of the tape comes opposite the contacts. A resilient strip 14, Fig. 4, may be arranged in the cassette to assist in coiling the tape as it is fed in through the passage 4, the strip 14 being pushed adjacent the wall of the interior 2 when the cassette is full. A plurality of such strips may be provided, Figs. 6 and 7 (not shown). Magnetic recording apparatus.-Fig. 8 shows a magnetic recording/playback apparatus in which the cassette 1 may be placed, the introduction of the cassette closing contacts 43 and 44, to energize a solenoid 58 which causes a plate 32 to rotate, thereby bringing a roller 24 into contact with, the inner edge of groove 25 in a disc 26 so that it is driven in one direction; at the same time solenoid 37 is energized to swing a belt 22 driven by roller 24 into contact with the tape 3 to drive it past record/playback heads 5. Movement of plate 32 moves a rod 30 controlling contacts which connect one of the heads 5 (or one group of heads) to an amplifier 73. When most of the tape has been withdrawn from the cassette, an aperture in the tape allows contacts 10 and 11 to meet and operate a reversing switch 93. This causes solenoid 57 to rotate the plate 32 so as to bring the roller 24 into contact with the outer edge of groove 25 so that it is driven in the opposite direction, and movement of the plate 32 causes the other head 5 (or group of heads) to be connected to the amplifier 73. When most of the tape has been fed back into the cassette, a further aperture in the tape allows contacts 10 and 11 to meet, thereby energizing an electromagnet 56 which releases the cassette and allows contacts 43 and 44 to open and restore the apparatus to its initial position.
